Abstract: An intravascular treatment device is presented having an expandable frame made up of circular struts, straight struts, and bent struts forming a frame with circumference that varies over the length of the frame. Radiopaque markers can be positioned on the bent struts to indicate outer circumferences of the frame along the length of the frame. The device can be a stent or a clot retriever. If the device is a clot retriever, the proximal end of the expandable frame can be attached to a guide wire and the distal end of the expandable frame can be free to slide over the guide wire when the frame moves from a collapsed state to an expanded state and vice versa.

Abstract: Balloon catheter devoid of guidewire or guidewire lumen and having a proximal shaft with only a single continuous lumen. A coil assembly is mounted at its proximal end to the distal end of the proximal shaft defining an interface therebetween. Disposed about a distal section of the proximal shaft and a proximal section of the coil assembly is a sleeve. A balloon, having a vent hole, forms a proximal leg seal about an outer surface of a distal end of the sleeve and an opposite distal leg seal. The sleeve covers the interface and extends axially in a distal direction terminating underneath the proximal leg seal of the balloon. A distal section of the coil assembly at least partially coincides with the distal leg seal of the balloon. A wire member secured at a plurality of connection points along the coil assembly extends axially within the balloon.

Abstract: Intrasaccular flow diverter including: an interior fill braid physically inverted over itself forming a proximal inverted end and an opposite free end; and a dome braid disposed distally of and secured to the interior fill braid. Subject to application of an external mechanical force, the dome braid is transitionable between an expanded state and a compressed state. The dome braid has a proximal end with an opening defined therein through which starting at the free end the interior fill braid is passable therethrough exerting a radially outward force on the dome braid. A delivery wire is releasably detachable from the proximal inverted end of the interior fill braid. The dome braid has a stiffer profile relative to that of the interior fill braid to maintain in position within the aneurysm the dome braid as the interior fill braid is advanced therein.

The delivery tube may include at least one segment at its distal end which includes a plurality of transverse slots. Each slot of the plurality of slots includes an origin on the perimeter of the delivery tube, a terminus closer to a central axis of the delivery tube than the origin, and a depth between the origin and terminus. The origins of at least two slots of the plurality of slots may be located at different angular positions relative to the central axis. The return conductor may be electrically insulated from and positioned within the delivery tube.

Abstract: Implant deployment systems can generally can include a braided implant that can be detachably attached to a delivery tube by an expansion ring that can be positioned within a notch on an outer surface of the delivery tube near a distal end of the delivery tube. The implant can be positioned within a lumen of the delivery tube and remain attached to the delivery tube as the assembly is fed through a microcatheter to a treatment site. Once the braided implant is implanted, the expansion ring can move from a collapsed configuration that is engaged with the notch of the delivery tube to a deployed configuration that releases the delivery tube, thereby releasing the braided implant from the delivery tube.

A second expansion ring can be connected to the distal end of the braid. Each expansion ring can include a frame that imparts an outwardly expanding radial force to the braid. The frame can include a plurality of elongate members interconnected by one or more intersections.

During delivery and manipulation of the implant, the securing ring can be held between the pusher and the securing feature of the securing wire with the securing wire and pull wire extended through securing ring. To deploy the implant, the pull wire can be retracted proximally to thereby allow the securing feature to pass through the securing ring and release the implant. The pusher can include a hypotube and/or an extended pushing feature on the securing wire.
